Turn on Business settings → Invoice preferences → Show product barcodes on invoices and every line item on your print invoice carries a small scannable barcode under the description. The classic use case: the customer's receiving clerk scans each line as the goods arrive, instantly catching wrong-quantity or wrong-product shipments before signing the delivery note.

Default is OFF (no surprise ink) and only renders for line items linked to a product in your catalogue — free-text lines render normally. Pairs naturally with the 📷 Scan flow for the inverse direction. Growth-tier.
